Abstract

An airbag module, in particular side airbag module, for a motor vehicle, is provided. The airbag module comprising a gas bag inflatable with gas to protect a person, a gas generator longitudinally extending along a direction of extension for releasing the gas required for inflating the gas bag, and a flat carrier for carrying the gas bag and the gas generator, wherein the carrier includes two legs which are connected with each other along the direction of extension and are located opposite each other transverse to the direction of extension, so that the carrier forms a receptacle open on three sides for the gas generator and the gas bag. The carrier comprises a flow-off region, through which gas emerging from at least one outflow opening of the gas generator can be flown off into an exterior space surrounding the airbag module.

Claims

1. An airbag module, in particular side airbag module, for a motor vehicle, comprising:

a gas bag inflatable with gas to protect a person,

a gas generator longitudinally extending along a direction of extension for releasing the gas required for inflating the gas bag, and

a flat carrier for carrying the gas bag and the gas generator, wherein the carrier includes two legs which are connected with each other along the direction of extension and are located opposite each other transverse to the direction of extension, so that the carrier forms a receptacle open on three sides for the gas generator and the gas bag,

wherein the carrier comprises a flow-off region, through which gas emerging from at least one outflow opening of the gas generator can be flown off into an exterior space surrounding the airbag module.

2. The airbag module according to claim 1, wherein the two legs are integrally molded to each other along the direction of extension.

3. The airbag module according to claim 1, further comprising a flexible protective sleeve of the airbag module, which at least partly surrounds the carrier, the gas generator and the gas bag, wherein in particular the protective sleeve is formed by at least two protective sleeve parts which for forming the protective sleeve are connected with each other, in particular welded or bonded to each other or connected with each other via a hook-and-loop fastener.

4. The airbag module according to claim 3, wherein the carrier is introduced into a pocket formed on the gas bag for fixing the gas bag on the carrier.

5. The airbag module according to claim 4, wherein the protective sleeve is connected with the gas bag such that the protective sleeve together with the gas bag forms said pocket for the carrier.

6. The airbag module according to claim 4, wherein for forming the pocket a flexible material layer, in particular of a gas bag material, is fixed on the gas bag, wherein in particular on that material layer or on the gas bag a through opening is provided, through which the carrier can be introduced into the pocket.

7. The airbag module according to claim 1, wherein the gas bag defines an interior space which can be filled with gas for inflating the gas bag, wherein in particular the carrier is arranged in the interior space of the gas bag.

8. The airbag module according to claim 1, wherein the gas bag is folded to a package arranged between the legs.

9. The airbag module according to claim 1, wherein the flow-off region is formed as a through opening of the carrier.

10. The airbag module according to claim 1, wherein on contact with gas flowing out from the gas generator the flow-off region forms a through opening of the carrier.

11. The airbag module according to claim 9, wherein the through opening of the carrier expands when gas flowing out from the gas generator flows through said opening.

12. The airbag module according to claim 1, wherein the gas bag includes at least one through opening communicating with the flow-off region of the carrier, so that gas flowing out from the gas generator can be flown off through the at least one through opening of the gas bag via the flow-off region of the carrier into an exterior space surrounding the airbag module.

13. The airbag module according to claim 1, wherein before inflating the gas bag the flow-off region is covered by a material region of a gas bag material, wherein in particular the material region is formed by a portion of the gas bag.

14. The airbag module according to claim 13, wherein during inflation of the gas bag the material region cooperates with gas flowing out from the gas generator such that a through opening is formed at the material region.

15. The airbag module according to claim 10, wherein the through opening of the carrier expands when gas flowing out from the gas generator flows through said opening.
